Node B is the graph's `facts` node (script diff_facts.py), not a node
named diff_facts. criterion_fault has no `next`; it reaches holistic
through the map join, so draw it dashed like the other branch-terminal
edges instead of as a solid successor edge.
A live run died at map_criteria: one heavy criterion exhausted
max_iterations (10) with no fallback and sank the whole 17-criterion
review. check_criterion now has a 30-iteration budget, a tool-budget
instruction, and falls back to criterion_fault, which records a
schema-shaped UNMET verdict with a PIPELINE-FAULT evidence marker for
that one criterion; verdict.py renders it as DIED rather than judged.
